With the weather what it is the past 2 days around my place I have taken a bit of a rest from workin to code a little something. Though its not quite done I thought I might share it with you folks and see what you think of it so far.Space Invaders 2022.
Controls are pretty basic;
Right and Left arrow keys move your defense cannon.
Space bar shoots.
it does track your score, but there is only the initial wave to fight off. Its pretty bare bones at the moment too, so there is only the one scale and no options.
It has some issues with the invaders freezing from time to time. Almost like a time stop special, which I wish I could say was the intent.
But alas I haven't quite figured out why they freeze for a very specific amount of time!There is also the occasional collision issue where your shot will pass through an Invader. Probably because I'm using a very VERY basic POINT approach to detecting if the shot hits an Invader, so if it happens to find one of the blank pixels in the invaders then it will tend to miss. Just haven't added a secondary POINT detection to help fix that.
The Invaders also cannot hit you with their weapons yet, so your invincible at the moment.
Beyond some special graphical elements I would like to add that about all that is left to finish.
Don't forget the MFI file too.
